Also, does it > need to go into v3.18 and be backported to stable? Or just v3.19. The original change [that is fixed now] is only scheduled for 3.19 and in Mark Brown's tree [0]. So there shouldn't be anything to do for you now.

Also, does it > need to go into v3.18 and be backported to stable? Or just v3.19. It's only needed in the regulator tree for 3.19, and does not need to be backported. We could convert the drivers (and dts) that currently use "<vendor>,system-power-controller" to use the new helper (while maintaining backward compatibility) after 3.19-rc1 is out.

Thanks for your feedbacks. I think that Mark will probably wait until there are more reviews on this serie.

In other words, I need more reviews and more positives feedbacks about this serie (as far as people who were against the previous ones). For example, Feedbacks from Felipe Balbi and Lucas Stach would be welcome.

It reverts commit a4b4e0461ec5 ("of: Add standard property for poweroff capability"). As discussed on the mailing list, it makes more sense to rename back to the old established property name, without the vendor prefix. Problem being that the word "source" usually tends to be used for inputs and that is out of control of the OS. The poweroff capability is an output which simply turns the system-power off. Also, this property might be used by drivers which power-off the system and power back on subsequent RTC alarms. This seems to suggest to remove "poweroff" from the property name and to choose "system-power-controller" as the more generic name. This patchs adds the required renaming changes and defines an helper function which checks if this property is set.
